The kin selection theory of genomic imprinting and modes of reproduction in the eusocial Hymenoptera

Biological Reviews, Volume 98, Issue 2, Page 677-695, April 2023., 2023
ABSTRACT Genomic imprinting is known from flowering plants and mammals but has not been confirmed for the Hymenoptera even though the eusocial Hymenoptera are prime candidates for this peculiar form of gene expression. Here, the kin selection theory of genomic imprinting is reviewed and applied to the eusocial Hymenoptera.

The complete mitochondrial genome of a parthenogenetic ant Monomorium triviale (Hymenoptera: Formicidae)

Mitochondrial DNA. Part B. Resources, 2021
Monomorium is one of the most species-rich yet taxonomically problematic ant genus. An East Asian species, M. triviale Wheeler, W.M., 1906, is reproduced by obligate thelytokous parthenogenesis and performs strict reproductive division of labor.

Structure of Bee Communities in Marginal Lands of the Puget Sound, USA. [PDF]

Ecol Evol
We surveyed wild bee communities in marginal lands of the Puget Sound, USA. Bee communities were highly diverse and stable across seasons, but were variable within seasons. ABSTRACT Wild bee communities in urban ecosystems are often challenged by habitat fragmentation and low floral diversity.

Genetic analysis reveals the putative native range and widespread double‐clonal reproduction in the invasive longhorn crazy ant

Molecular Ecology, Volume 32, Issue 5, Page 1020-1033, March 2023., 2023
Abstract Clonal reproduction can provide an advantage for invasive species to establish as it can circumvent inbreeding depression which often plagues introduced populations. The world's most widespread invasive ant, Paratrechina longicornis, was previously found to display a double‐clonal reproduction system, whereby both males and queens are produced

The Existence of Deuterotokous Reproduction Mode in the T. tabaci (Thysanoptera: Thripidae) Cryptic Species Complex

Journal of Horticultural Research, 2020
The present study aimed to investigate whether adult males could fertilize immature female pupae in the leek (L1) and tobacco-associated (T) Thrips tabaci lineages and to investigate the potential effects of mother to son inbreeding on the appearance of ...

Revisiting the hymenopteran diploid male vortex: a review of avoidance mechanisms and incidence

Entomologia Experimentalis et Applicata, Volume 170, Issue 12, Page 1010-1031, December 2022., 2022
The Hymenoptera (bees, ants, wasps, and sawflies) have haploid males and diploid females. According to the diploid male vortex (DMV) theory, inbreeding increases sterile diploid male production and extinction risk for many species. We reviewed DMV incidence and avoidance.

Complex population structure and haplotype patterns in the Western European honey bee from sequencing a large panel of haploid drones

Molecular Ecology Resources, Volume 22, Issue 8, Page 3068-3086, November 2022., 2022
Abstract Honey bee subspecies originate from specific geographical areas in Africa, Europe and the Middle East, and beekeepers interested in specific phenotypes have imported genetic material to regions outside of the bees' original range for use either in pure lines or controlled crosses.

Cytogenetic mechanism and genetic consequences of thelytoky in the wasp Trichogramma cacoeciae [PDF]

Heredity, 2004
In Hymenoptera, complete parthenogenesis, that is thelytoky, is a common phenomenon where virgin females produce only daughters. Thelytoky is often induced by bacteria of the genus Wolbachia, but can also be genetically determined by the insect itself, as in the genus Trichogramma where both forms exist. In order to compare these two forms of thelytoky,

Asexual reproduction in introduced and native populations of the ant Cerapachys biroi. [PDF]

, 2012
Asexual reproduction is particularly common among introduced species, probably because it helps to overcome the negative effects associated with low population densities during colonization.

Spontaneous parthenogenesis in the parasitoid wasp Cotesia typhae: low frequency anomaly or evolving process?

Peer Community Journal, 2022
Hymenopterans are haplodiploids and unlike most other Arthropods they do not possess sexual chromosomes. Sex determination typically happens via the ploidy of individuals: haploids become males and diploids become females.
